Cold War Zombies Sail 630 Nuclear Bug

Treyarch have responded to reports of Black Ops Cold War Zombies players receiving the ‘Sail 630 Nuclear Bug’ error code and having their accounts permanently banned afterward.

In a new update on April 16 on Reddit, Treyarch Community Manager has stated that they investigated the issue even further and have identified a number of bans caused by this bug that will be reversed.

He states that not all bans have been reversed, as some very in fact legitimate bans in the mode, but many have after a security enforcement review.

Foxhound commented on a Reddit post with the latest statement from the studio:

Hello! The Sail 630 Nuclear Bug notice is indeed a disconnect message as previously shared and now noted by your peers. If you are disconnected mid-match, this error has the potential to show up.

We have an update to share: recent account enforcements have been reviewed and, where appropriate, accounts believed to be operating in good faith have been restored. Accounts that included additional flags for exploits will retain their enforcement.

As always, we encourage everyone to enjoy Zombies on PC within the terms of service.

He followed up further after a user commented asking why they decided to “lie” initially. Foxy replied that he provided the latest information he had at the time, but after further investigations things changed.

We’ve always relayed the most recent information available at the time of postings. According to the data available to us, accounts that have retained their enforcement are verified to have broken the Call of Duty: Black Ops Cold War Security and Enforcement Policy. Accounts believed to be operating in good faith have been restored.

He also reiterated that PC players are “safe” to continue playing Zombies in Black Ops Cold War.

As we mentioned above, you’re safe to enjoy Zombies on PC within the terms of service. No worries about going for high rounds!

Original Story:

In the early days of Black Ops Cold War, Zombies players were having their World Record runs abruptly ended by consistent crashes. Now, a new error code has been kicking Zombies players back to the menu, and they claim their accounts are permanently banned when they log back on.

Since April 2nd, the ‘Sail 630 Nuclear Bug’ has been crashing PC players’ Zombies games when they’re on high levels. Reddit user Korlesa was allegedly banned after receiving this code and posted to the CODZombies subreddit to highlight the issue.

In the post titled, “People are being falsely banned while going for high rounds in Zombies on PC,” Korlesa described how “after going 50+ rounds people are receiving a “Sail 630 Nuclear Bug” Error. Upon exiting to Battle.net we see that we have been permanently banned.”

Before the post was locked, to back up their claim, Korlesa compiled over 70 posts to the Activision Support page in which players reported they had been falsely banned after receiving the Sail 630 Nuclear Bug.

Korlesa summed up these reports highlighting what the majority of them had in common:

  • They were on PC
  • They were playing Zombies
  • They were on a high round (50+)
  • They received the same error (Sail 630 Nuclear Bug)

Treyarch’s Community Manager, Josh Torres, aka FoxhoundFPS, replied to the Reddit post. “I’m unable to assist with this issue,” he said. “All infractions undergo a thorough review process by the security team before enforcement.”

Black Ops Cold War Zombies

However, the original post and the CODZombies subreddit continued to be flooded with players reporting the issue and worrying if they’re safe to play. After a concerned Zombies fan asked if they should avoid playing the game until the issue has been fixed, FoxhoundFPS replied with a full statement.

We are aware that some players are seeing the Sail 630 Nuclear Bug message and then are unable to connect while seeing a ban message. The ban message is not a product of disconnect errors. For questions about enforcement policies, please visit this link.

I’ve spoken with our teams regarding the recent Sail 630 Nuclear Bug threads and reports, and here’s what I have to share.

Sail 630 Nuclear Bug: This error string is currently presented instead of the standard disconnect language when a disconnect occurs in the Zombies menus on PC. PC players would typically see, “Connection to the Blizzard game server has been lost. Please exit and try again. BLZBNTBGS000003F8.”

We encourage players to continue playing Zombies as per usual, which includes chasing high-rounds and personal bests.

After another user asked if players who have been banned after seeing the error message will get their accounts back, FoxhoundFPS reiterated his statement.

I stated in my post that the bans are not the result of the disconnect or the disconnect error. The recent enforcements are not bugs or errors.

Players that experience disconnects are not subject to enforcement unless they are violating the Call of Duty: Black Ops Cold War Security and Enforcement Policy. As I have always stated, all infractions undergo a thorough review process by the security team before enforcement.

Players are able, and encouraged, to maintain or resume normal Zombies gameplay.

To summarize, Torres passed on players’ concerns to the security team, who then said that the Sail 630 Nuclear Bug is a standard error message unrelated to player bans.

A brand-new melee weapon is coming to Black Ops Cold War and here’s everything you need to know about the Scythe, including how to unlock it.

It can be fun to rack up kills from a distance with an Assault Rifle after hopping into a game of Black Ops Cold War, and sometimes it’s more exciting to use a melee weapon to battle your enemies up close.

Treyarch accidentally released the Scythe melee weapon in Black Ops Cold War in a surprise update on June 6, giving players a sneak peek at the weapon. Now there is an official release date for the Scythe in Black Ops Cold War, so here’s how you can unlock it.

How to unlock the Scythe in Black Ops Cold War

The Scythe will be released for Call of Duty: Black Ops Cold War on August 12, 2022.

Here’s how to unlock the Scythe in both Multiplayer and Zombies:

  • Multiplayer – Using a Melee weapon, get 2 kills while Ninja or Dead Silence are active in 15 different completed matches.
  • Zombies – Using a primary Melee weapon, kill 200 enemies while Insta-Kill is active.

Completing 15 multiplayer matches will take some time, so you might be faster jumping into a game of Zombies.

The in-game description says that the Scythe is a “quick swinging” two-handed melee weapon that allows you to “reap a bountiful harvest by cutting down all who stand in your path.”

Best UGR loadout for Black Ops Cold War

The UGR is a brand-new SMG in Black Ops Cold War, so here’s our best compelte with Attachments, Perks, and Equipment.

Best UGR loadout in UGR

The UGR is a brand-new SMG in Black Ops Cold War, and players can’t wait to try it out in multiplayer matches. Here’s our breakdown of the best UGR loadout to run in BOCW.

Even though CoD Vanguard is now in its third season, and Modern Warfare 2 is arriving this year, support for Black Ops Cold War is still going strong. After a huge Zombies patch on April 25, Treyarch have now added a remastered version of the Jungle map, as well as a new weapon.

The UGR SMG is an interesting close-range option, as it’s an “underwater rifle modified for improved land performance.” It doesn’t have the bullet velocity to take enemies out at distance, but it’s formidable in close-quarters combat.

If you’re looking to run it in multiplayer, you’ll need to know how to make the most of it. Check out our best UGR loadout for Black Ops Cold War.

Best Cold War UGR loadout attachments

Operator underwater using UGR
  • Barrel: 12.8″ VDV Reinforced
  • Underbarrel: Spetsnaz Grip
  • Magazine: Explosive Flechettes
  • Handle: GRU Elastic Wrap
  • Stock: KGB Skeletal Stock

We kick things off with the 12.8″ VDV Reinforced Barrel to seriously boost the UGR’s bullet velocity and damage range. The UGR is severely lacking in both departments, but this attachment makes it far more competitive in longer-range battles.

Next up, we went for the Spetsnaz Grip to keep the recoil in check and make it far easier to control. Then we chose KGB Skeletal Stock and GRU Elastic Wrap for a decrease in sprint-to-fire time and ADS speed, allowing you to get shots earlier while rushing around the map.

Many were surprised to see that the UGR comes with explosive rounds, so we couldn’t resist equipping Explosive Flechettes to our loadout. Aside from the obvious boost in overall damage, they also increase ammo capacity which is vital in a fast-firing weapon.

Best Cold War UGR Perk & Equipment

Flak Jacket Perk in BOCW
  • Perk 1: Flak Jacket & Tactical Mask
  • Perk 2: Scavenger & Assassin
  • Perk 3: Ghost & Ninja
  • Lethal Equipment: Semtex
  • Tactical Equipment: Stimshot

We think the UGR is still effective with only five attachments, so we’re equipping Greed Wildcard to use extra Perks in each slot in BOCW multiplayer matches,

Flak Jacket and Tactical Mask are incredibly important in the first slot, as they’ll keep you protected from incoming explosives and Gas Mines, which can be frustrating when running and gunning.

Next, we picked Scavenger to make sure you never run out of ammo, as well as Assassin to keep the Scorestreaks rolling in. In the final slot, we recommend Ghost to stay invisible on enemy radars, as well as Ninja to help with flanking, which you’ll want to do a lot of with the UGR.

In terms of equipment, Semtex is an easy-to-use lethal, while Stimshot will give you a handy health boost when things get tough out there.

How to unlock UGR in Black Ops Cold War

UGR in Warzone

To unlock the UGR SMG, players must kill an enemy revealed by their Spy Plane, UAV, or Field Mic with an SMG in 15 different completed matches. If you’re not a big multiplayer fan, it can be earned in Zombies by eliminating 1000 enemies while using an Epic rarity or better SMG.

You can also bypass the challenges altogether if you don’t mind spending 2,400 CoD Points on the new Lazar bundle.

Best alternatives to Cold War’s UGR

Black Ops Cold War has some powerful SMGs if the UGR isn’t working for you. The TEC-9 and LC10, in particular, remain incredibly strong in multiplayer matches and rank as two of the best weapons in the entire game.

UGR unlock Warzone cold war

Treyarch continue to release new weapons for Cold War and the latest is the UGR SMG based on the APS underwater rifle that will be making its way to both Cold War and Warzone. Here’s how to unlock the UGR in Cold War and Warzone.

Although Vanguard is now in Season 3 and 2022’s Modern Warfare 2 has been announced, Treyarch are still releasing content for 2020’s Black Ops Cold War. Alongside a ton of Zombies changes that arrived with the April 25 update, Treyarch confirmed the classic Jungle map and a brand-new weapon would arrive in the “coming weeks.”

On May 6, the new UGR SMG made its way to the game alongside a remastered version of the Jungle map. Here’s how to unlock the UGR in Cold War and Warzone.

UGR SMG in Cold War & Warzone

Those who played Call of Duty: Ghosts may recognize Cold War’s new UGR SMG as it’s based on the APS underwater rifle that appeared in the campaign. The in-game description says it’s a “full-auto submachine gun” and an “underwater rifle modified for improved land performance.”

The weapon is projectile-based with quite a low bullet velocity, so you won’t be beaming enemies at range with ease. Players were also surprised to see that it comes with explosive bullets.

How to unlock UGR in Cold War & Warzone

Players can unlock the UGR by killing an enemy revealed by your Spy Plane, UAV, or Field Mic with an SMG in 15 different completed matches. You can also unlock the UGR in Zombies if you eliminate 1000 enemies while using an Epic rarity or better SMG.

The new UGR SMG has the same unlock challenge for both Cold War and Warzone, so it’ll be up to you to decide which game you’d like to complete it in. In addition, you can also receive the UGR straight away by purchasing the new Lazar bundle for 2,400 CoD Points.


The Nikita AVT and M1916 have also arrived in Warzone with Season 3, so you can check out how to unlock the new Assault Rifle and Marksman Rifle.
